COMBINED GI IURN AND BUTTER-WORKER.

To all whom it may concern:

Be it known that I, Animus M. Knunsnnr a citizen of Jutland, Denmark, residing at lVest B1H11Cl1,'111 the county of Cedar and State of Iowa, have invented certain new and useful Improvements in. Combined Churns like or corres aondin arts throu 'hout the l a: b

mounted for rotation.

and Butter-Workers, of which the following is aspecification. i

This invention relates to improvements in combined churns and butter workers; and the objects I have in view are. to provide a simple, sanitary and inexpensive machine which can be usedtfor. churning, and in which, after the churning is completed, the butter can be quickly worked.

A further object of the invention contemplates the provision of means in the nature of specially devised mechanism whereby the rotation of theseveral rollers employed in connection with my invention may be operated, when occasion demands, from one and the same source of power as that employed for driving or operating the drum or cylinder within which the said paddles are arranged. V

The above and additional objectsare accomplished by such means as are illustrated in their preferred embodiment in the accom: panying drawings, described in the following specification and then more particularly pointed out in the appended claims forming a part of this application.

1n describingthe invention in detail, reference will be had to the accompanying drawings,- wherein like characters denote several views and in which:- Y

Figure 1 is an end view of a machinecon structed in accordance with my invention; Fig. 2 is a longitudinal sectional view, parts being shown in elevation; Fig. 3 is a section on the line 33 of Fig. 2; and Fig. at is a top plan view of themeans employed for controlling the rotation of the roller or paddle embodied in my invention.

Referring now to the drawings wherein is illustrated the preferredembodiment of my invention, the numeral 1 designates the base of a suitableupright frame 2, between the ends of which a closed-end cylinder or drum 3 forming a part of my invention is A shaft 4 extends "longitudinally from one to the other of the Specification of Letters Patent.

sleeve 5 extending throughout the length of i the drum 3 and embracing the said shaft 4.

Rollers 6 arranged in pairs, extend longitudinally of the drum 3, the said rollers bemg mounted for rotation upon spindles 7 secured thereto or formed integrally therewith, the latter being journaled in the ends of the drum 3, one of the spindles of each roller projecting exteriorly thereof, the extended end of the said spindlesbeingmounted for rotation within a suitable bracket 8 secured as at 9 to the said drum end 3 through which the spindle extends. Motion is imparted to the rollers 6 through the medium of a pinion 1O keyed or otherwise fixedly secured to a sleeve 11 loosely mounted for rotation upon the shaft 4, the said pinion meshing into gear wheels 12 which in turn mesh into similar gear wheels 13, the latter (the said gear wheels 12 and 13) being mounted upon the spindles 7, above mentioned. A second gear wheel 14 is secured to the sleeve 11 in spaced relation to the 'plnion 10, the said gear wheel 14 meshing into a comparatively large gear wheel 15 mounted upon a sleeve 16 disposed to embrace a shaft 17 extending parallel with the said shaft 4:. A second gear wheel 18 is mounted upon the said sleeve 16, the latter meshing into a gearv wheel 19 mounted upon the said shaft 1, this arrangement of the gears permitting the several rollers 6 cmbodied inmy invention, to be rotated alternately in opposite direction during the retation of the drum 3 within which they are disposed. A crank handle 20 is formed upon one end of the shaft 1 for imparting motion thereto, however, any other suitable means may be employed for the purpose of driving or imparting motion to the said shaft.

Paddles 21 comprising a pair of hingedly connected boards or strips 22 are arranged within the drum 3 adjacent the rollers 6, the said paddles being disposed diametrically opposite and slightly out of alinement with the said rollers. One of the said boards or strips 22 of each paddle is hingedly connected as indicated at 22 to the other of the said boards or strips, while the latter is fixedly secured as indicated at 23 to theinterior wall of the drum. During a butter working operation, motion is im parted to the shaft 1 for rotating the drum 3 in one direction and driving the several rollers alternately in opposite directions,

this being 'accon'iplished by the gear mechanism above described. As'the drum 3-1-0 tates, the paddles 21 open and close by reason of their hinge connection to ma tcrially assist in the saidoperation.

When it is desired that the rollers 6 should remain idle, that is, incapable of r p that the form ofmy' invention, illustrated ta'tion on their own axes, and this is necessary during a churning operation, the gears and 18 are thrown out of mesh with the gears 14k and 19 thereby permitting the said drum 3 to be rotated irrespective of independent I rotation of the rollers 6'. -The means employed. for shifting or throwing the said gears 15 and 18 out of mesh with the gears 14 and 19 comprises a substantially Ill-shaped bracket 23 pivotally con- 'nected as at 24 toone of the upright portions 2 of the frame through the medium of a pin 25 extending transversely therethrough. A handle 26 i formed uponone end of the bracket for raising and lowering the latter as occasion demands, this operation swinging the said gears out of mesh and thereby permitting the drum 3 to be rotated in the desired manner. A quadrant 27 may be secured to the upright frame por- 'tion 2 and engaged by a pivoted lever 28 carried by the bracket, 23 for locking the said bracket in adjusted position, the detail arrangement of the lever 28 and the bracket 23 being clearly illustrated in F igsi 1 and 1 of the drawings.

During a butter working operation, the rollers 6 are in motion and the butter is carried or conveyed by the paddles 21, this movement being as followsz-One of the "paddles 21 first lifts or carries the butter up-,

wardly until the saidpaddle, by the continued rotation of the drum, begins to descend, whereupon the butter by reason of gravity, drops or falls upon the roller 6 and as the latter are in motion, it is thoroughly Stops 32 are provided against which the boards 22 comprising the paddles 21 fall to prevent the same from engaging the inner periphery of the drum and at all times supporting the said boards in a manner necese sary to the operation of the paddles.

It will be seen from the above, taken in connection with the accompanying drawings, that the operation of the rollers. 6 iscontrolled by the manipulation of the handle 26, of the bracket 23; that by shifting or adjusting, the said handle, the gears 15 and 16 may be thrown out of mesh with the cure by Letters Patent is-:-

gears l t and 19, permitting thedium, 3 to effectually work the butter during the-butter 1 working operation in the desired'manneri- In reduction to practice, .I have found in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical yet, realizing that the conditions concurrent with the adoption o-fmy device will necessarily vary, I desire tolemphasize' the. fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when requiredfwithoiit sacrificing any of the advantages of my. invention, a defined the appendedclaims. a

Having thus fully describedmy inven-u tion, what I claim as new and desire-to se- 1. In a combined. churn butter- :worker, a rotatable drum, means rotatable within said drum, a

plluralityof gears operating exteriorly of t e fclrum to. rotate the one of the said plurality of gears to actuate said means, a drum uponl'which said first mentioned gear is loosely mounted, a"

In a combined churn "and butterworker, a rotatable drum "means rotatable within the drum, a. lura lity ofv gears operating exteriorly of; the drum to rotate said means therein, afi'rst, gear engage'able with two of'the said plurality. of gears, a 3' drum shaft upon whichthe' sa id firstgean is loosely mounted, said ,drum shaft being a rotatable to actuate'saidi drum, a second gear rotatable with said first gear, a third gear upon said drum'shaft, a-"bracket' 111 crumed to the support meansfor thedrum, a sleeve rigid with the bracket, a shaft op.
